[Follow up examination of the endometrium during tamoxifen therapy].
Tamoxifen is a non-steroidal estrogen antagonist used mainly in the adjuvant therapy of breast cancer. Tamoxifen acts primarily as an antiestrogen, but also carries estrogenic effect, mainly to the endometrium. Although diverse pathological uterine findings has been described in connection with the long term use of this drug, there is no widely accepted protocol for the monitoring of the endometrium in these patients. All patients referred for gynecologic examination at the Department of Obstetrics and Gynecology University Medical School Debrecen, Hungary with previous treatment for breast cancer were involved in a screening programme. The gradual screening programme consists of: transvaginal sonography, color doppler imaging, hysteroscopy, and endometrial curettage or sampling. If any of the first steps proved to be negative, further evaluation could be avoided. Altogether 31 patients were referred for examination and transvaginal sonography alone excluded endometrial abnormality in 9 cases, while the rest of the patients went through further evaluation. The ratio of false positive results using transvaginal sonography alone was high and could be lowered with additional color doppler imaging. Endometrial pathology could be excluded in about 50% of cases without tissue sampling. Positive histology was found in 25% of patients receiving Tamoxifen. The most frequent pathological finding was endometrial polyp. In conclusion endometrial changes found by transvaginal sonography, should be further evaluated. The gradual screening procedures enable us to the proper use of more invasive procedures.
